For consumers that desire a sports sedan with plenty of performance, the 2018 Infiniti Q50 seems to be the obvious option. After all, the newest lineup is hailed as “luxury that thrills,” but the excitement is more than owners bargained for. This model has a failing electrical system, defective engine and poorly constructed wheels.

Problems with the Electrical System

The main part of a vehicle’s electrical system includes the battery, starter and alternator, but the power runs throughout the entire car. When this system malfunctions, nuisances abound.

One NHTSA complaint talks about the problems. “The contact owns a 2018 Infiniti Q50. The contact stated that the back-up screen would not display while the gear was in reverse. The cause of the failure was not determined. [Dealer] and the manufacturer were notified of the failure, but no assistance was offered. The contact was informed that the vehicle was included in the NHTSA Campaign Number 19V654000 (Electrical System). The contact stated that the vehicle experienced the same failure listed in the recall. The failure mileage was 30,000.”

The recall being referenced states that the back-up camera doesn’t have an image, which increases the chance of an accident. This problem affects more than one million vehicles. Owners might as well close their eyes before backing up. They might have a better chance of entering traffic than allowing themselves to be distracted while fiddling with the back-up camera. It’s just one way that this model aims to “thrill” the occupants.

Problems with the Engine

A car engine can make or break the vehicle. If the motor is powerful and reliable, the ride is enjoyable. Otherwise, it can be cumbersome and downright dangerous.

That’s what is shown in this NHTSA comment. “The car caught fire under the hood and completely burned up in the parking lot as I was exiting the vehicle.”

While this is scary, there’s another occurrence that’s happening with the Q50. NHTSA Campaign Number 17V476000 states that the fuel pump control module software might be defective in over 14,000 vehicles. This defective software allows the fuel level to drop too low to supply the engine, leading to a stalling situation while driving. If this occurs, the vehicle is at risk for an accident. While it’s unclear what caused the car fire above, it’s evident that Infiniti has found multiple ways to create “thrills” for owners. Either stalling in the middle of the road or having the sedan burst into flames is sure to gain attention.

Problems with the Tires

It’s rare to see a wheel or tire-related complaint on a newer vehicle. For the most part, this is one area that automakers have perfected and can’t really fail at, except for with the 2018 Infiniti Q50.

Another NHTSA complaint states, “Run flat tires went flat on a pothole that was not even realized on a Sunday with no service station open. Even if they were, the tire has to be replaced, cannot be repaired. There is no spare tire option – when contacted, company refused ‘not possible.’ This is not safe at all and must be addressed. Must have a spare tire especially since run flat tires cannot be repaired and are not in stock at most service stations.”

The run-flat tire should have gotten the owner at least ten miles, but probably more with the equipment Infiniti includes. For the premium price of this vehicle, it’s disheartening to see the lack of care for occupants, as this situation could have led to a major accident. Of course, the automaker has nothing to say about the situation and has chosen to act like it didn’t happen. In the meantime, owners are driving around, experiencing maximum “thrills,” completely unaware that the tires could put them in danger.
